Description of Products

Hitachi is a leading global diversified technology and manufacturing company, particularly in the air conditioning and refrigeration industries, where Hitachi's scroll compressors enjoy a high reputation for their high efficiency, reliability and environmental friendliness.


Hitachi is committed to the development and production of high-efficiency scroll compressors for a wide range of applications in domestic air conditioning, commercial air conditioning, heat pump systems, and refrigeration and freezer equipment. Through continuous technological innovation and strict quality control, Hitachi scroll compressors not only meet the market demand for high energy efficiency, but also provide users with quieter and more reliable refrigeration solutions.

Naming Rules of HITACHI Scroll Compressors 

 

 

Working Principle

Scroll compressor is generally through the pairs of staggered 180 degrees of the screw thread mutual movement formed from the outside to the inside of the compression cavity continuously shrinking changes, to achieve air compression. In the suction, compression, exhaust work process, fixed disc fixed in the frame, moving disc driven by the eccentric shaft and anti-rotation mechanism constraints, around the centre of the base circle of the fixed disc, for a very small radius of the plane swing. With the conventional reciprocating rotary compressor is different, the two screws relative movement gap is small but not contact, the two screws relative movement of the linear velocity is low.

Features of Products

(1) Asymmetric scroll disc technology  
High efficiency and energy saving:
Hitachi adopts a unique asymmetric scroll profile design to optimise the refrigerant flow path, reduce gas leakage and improve compression efficiency (COP up to 3.25 or more).  
Low Vibration & Quiet: Small pressure difference between adjacent compression chambers for smooth operation and noise as low as 60dB(A).  
Long life: Few moving parts, low friction loss, high reliability, suitable for long-term operation conditions.  


(2) EVI Enhanced Vapour Injection Technology 
Enhancement of low-temperature heating capacity:
Improvement of refrigerant flow through intermediate make-up air, so that the unit can still operate stably in -25℃ environment, and the heating capacity is increased by 25%.  
Adaptation to wide temperature range: Suitable for heat pump systems in cold areas, reducing the attenuation of heat production.  


(3) Oil film sealing technology
Non-contact lubrication:
A sealing oil film is formed between the dynamic and static scroll discs by lubricating oil, reducing mechanical wear and improving energy efficiency and life.  
Internal oil separation technology: The oil return rate is as high as 99.99%, ensuring the stability of the lubrication system and reducing the loss of refrigerant with oil.  


(4) Release valve technology 
Preventing over-compression:
Under part-load conditions, the pressure is adjusted through the release valve to avoid overloading the compressor and improve energy efficiency and stability.
